Source notes & limitations
Started 1978, triennial/quadrennial. Tracks appliance ownership (refrigerator, washing machine, air conditioning) and housing characteristics. AC diffusion: 1993 RECS 68%, 2009 RECS 87%, 2015 RECS 87%. Useful for diffusion and home panels as complement to AHS.
Where this source appears
12 records across 6 decades and countries. Documented gaps are included; a source cited for a gap does not establish a value.
0 of 12 records have a current source audit. A transcription check reads a declared numeric field from a pinned local source file; a calculation replay reads its operands and applies the declared method and rounding rule. A source audit does not independently validate the source or every claim in a record. The date is the last successful local audit; the build checks that its bindings still match.
